[0037] Furthermore, the positioning holes correspond to the positions of the relays and fuses in the electrical box 13 , and the positioning holes correspond to the positions of the positioning protrusions 15 .

[0038] like Figure 7 , Figure 8 As shown, this embodiment adopts a manual pressing installation method, and a push-pull handle 16 is set on the side wall 4 of the outer frame 2. The outer frame 2 is moved forward and backward by using the push-pull handle 16. When the personnel place the electrical box 13, relays and fuses into the electrical box fixing module 12, the outer frame 2 is moved to the rear end, which does not affect the employees' installation line of sight and is convenient for placement; when the installation is completed, the personnel moves the outer frame 2 to the front end and proceeds to the next step.

[0039] In this embodiment, a pull rod 11 is provided on the outer side of the side wall 4. The pull rod 11 is connected to the turntable 9 through a connecting shaft, driving the turntable 9 to rotate, thereby driving the connecting rod 10 to move. The connecting rod 10 is connected to the limit plate 7, so that the limit plate 7 can move up and down in the limit groove 6, and the vertical connecting rod 5 is driven to move up and down through the limit plate 7 to complete the pressing and lifting actions.

[0040] In order to install the fuse and relay into the electrical box and avoid misalignment and crooked insertion, the present embodiment needs to limit the electrical box 13, relay and fuse. In the present embodiment, an electrical box fixing module 12 is provided. The electrical box fixing module 12 is a shell structure with a cavity inside and an opening at the top. Therefore, the electrical box 13 can be placed into the electrical box fixing module 12 to limit the electrical box 13; then the fixing template 14 is used to limit the relay and fuse. Specifically:

[0041] A contoured groove is provided at the bottom of the fixed template 14, and the contoured groove is horizontally fitted with the upper surface of the electrical box 13 and will not move left and right or front and back, thereby realizing the limitation of the components on the upper surface of the electrical box 13; a positioning hole is provided on the fixed template 14, and the positioning hole corresponds to the position of the relay and fuse in the electrical box 13 one by one, and a small amount of margin is left around the hole to ensure that the relay can be easily inserted and ensure that it will not shake and cause oblique insertion, so as to limit the relay by using the positioning hole; put the fuse into the positioning hole, and use the one-to-one correspondence between the positioning protrusion 15 and the positioning hole to realize the limitation of the relay and the fuse.

[0042] Through the above design, a multiple limiting structure is realized, which can not only facilitate the quick alignment of the fuse and the relay to the hole position, but also effectively limit the fuse and the relay during the pressing process of the pressing template 8 to prevent crooked insertion.

[0043] In order to facilitate disassembly and assembly, the fixed template 14 is detachably connected to the electrical box fixing module 12, and a locking mechanism is arranged around the fixed template 14 to lock with the electrical box fixing module 12 below.

[0045] The pull rod 11 operated by the staff is driven by the turntable 9 and the connecting rod 10. When the staff operates the pull rod 11 to press down and reset, the pressing template 8 can move up and down; and U-shaped limit grooves 6 are opened on both sides of the outer metal frame to ensure that when the pressing template 8 moves to the lowest position, the hand pull rod 11 can be restricted from continuing to move downward, and the downward stroke is limited, so that the relay will not be over-pressed. Through the above design, both the assembly efficiency and product quality can be improved.

[0046] More specifically, the connecting rod 10 includes a first rod and a second rod, wherein the first rod is disposed on the surface of the turntable 9 , the second rod is hinged to the end of the first rod, and the end of the second rod is connected to the limiting plate 7 .

[0047] The positioning protrusion 15 is slidably connected to the positioning hole, and when pressed down to the right position, the fuse is pressed down into the relay. By designing the height of the positioning protrusion 15, the preset pressing depth requirement can be met.

[0048] The relay pressing template 8 is made of plastic material, and the thickness ensures that it will not be easily deformed, thereby avoiding uneven distribution of pressing force.

[0049] In order to facilitate taking and placing, a strip groove 17 is provided on the front side wall of the electrical box fixing module 12, and the strip groove 17 passes through the top opening. In this embodiment, the number of the strip grooves 17 is 2, and the main function of the grooves 17 is the wire harness outlet.

[0050] The electrical box is taken in and out mainly by fixing the plurality of spring pins in the module 12. After the relay is installed, the locking mechanism is opened and the spring pins will pop out the electrical box to a certain height.

[0051] In terms of specific connection relationship, the operating table 1 is provided with slide rails on both sides, and the side wall 4 is provided with a slider at the bottom, and the slider and the slide rails are slidably connected.
